I just recently noticed that if I select a route in navigation then try to watch a movie from my ipod or view the rearview camera a still picture of the map shows instead of video feed. then if I back out and try again then a picture of the menu screen is up. the whole time I can hear sound but no video. I have a f90bt with 3.01 installed and hardwired bypass. Thanks in advance for your help. the only way to get rid of this problem is to turn off car and shut radio down.
